I'm not clear how this would work for me yet. I
probably don't want to replace my service from NTL
since I get my UK phone and broadband on the same
cable.

What I'd like is to just use a hand set to appear as
if I am a US local caller when I have to deal with
my US clients. I beginning to think this won't work.
When at home I'd need this:

handset -> box -> my firewall -> over the Atlantic -> Vonage
and on to the phone system -> client

And how would it work when I am travelling in the US?

handset -> T22 -> box -> hotel firewall -> over the Atlantic the other
direction -> my firewall -> switch box -> my firewall -> again over
the Atlantic -> Vonage and on to the phone system -> client?

I'm not at all clear how this gets set up. I know I'm
thinking like H323 here with my own switch inside my
home LAN in Belfast and that doesn't quite sound like
how this work.

My home Linux firewall is not something I'd think I
could replicate with someone else's idea of a home
user's router... I've got FreeSwan tunnels, local DNS,
snort, etc, etc...
